Pen Refill Trimming Guide Tool (Parker G2 Pilot G2)

This is a guide to assist you in trimming down pen refills to Parker G2 and Pilot G2 lengths.

Just insert your refill tip first into the groove until the tip touches the wall, then trim to your desired length using a razor blade. 

The slot cut out is Parker G2 length (cut right up to the slot face closest to the tip) and the end of the tool is Pilot G2 length.
